IMPROVEMENT IN HINGES FOR AWNING-BLINDS.

Specification forming part of Letters Patent No, 188,793, dated March27, 1877 application filed J annary 20, 1877.

To all whom it may concern Be it known that I, JOHN JAMES GREEN- OUGH,now residing in Syracuse, New York, have invented an Improvement inHanging Window-Blinds and Similar Structures, which I denominate AwningBlind Hinges, of which the following is a specification:

My improvement relates to the hanging of outside -blinds or shutters onbuildings so as to be opened and shut in the ordinary way, and also toserve the further purpose of an awning by swinging outward their lowerends when the blinds are shut, on horizontal pivots, into an inclinedposition for an awning, and readily returning them to their verticalhinges.

It consists in a peculiar double-pivoted hinge above a hook-joint, and anovel form of slotted detaching-hinges at the bottom, for readilyconverting the blind into an awning, as hereinafter more fully describedand definitely claimed.

The construction of hinges for this may be as follows, referring to thedrawing annexed, in which the details are shown.

Figure 1 represents a blind in the position of an awning; Fig. 2, partsof the double-pivoted hinge detached; Fig. 3, parts of theseparating-hinge detached; Fig. 4, hook or catch joint for the outeredge of the blind at top on line with hinge.

The parts of the double-pivoted or upper hinge are three in number, Abeing the part afiixed to the window-frame at the top, and consisting ofa plate to be fastened onto the window-frame.

This may be varied in form' for ornament, or to conform to the part towhich it is to be affixed.

A socket or thimble,'a, projects from this plate a distance determinedby its position, as well known to builders. B is a pintle that fits intothe thimble. The head of this pintle is turned up on one side at rightangles vertically with a horizontal stud, b, projecting from it, on theupper side of which a catch projects. The part 0 consists of a flatplate for fastening to the blind, with a righbangled projection, c, fromits vertical edge, through which a hole is made to receive stud b. Tolook them together, the stud enters the hole upside down, and is thenturned into place.

It is obvious a rivet may be substituted for the stud b to joint theparts B and G together.

to the side of the window-frame near the bottom, and having a thimble orsocket projecting from it, similar to the one a on the other hinge, butwith a slot, d, cut through its front side; and if it is made to fastenback, the hole is made oblong instead of cylindrical, and a horizontalcatch-plate projects back from it, with a notch, d, in it. The otherpart, E, of the hinge is a flat plate having a horizontal projection, 6,cast on it, from the under side of which a pintle, 0, projects, thatenters the socket in which it turns. This pintle e being of largerdiameter than the slot (1, it is flattened or scarfed off on one side,so as readily to slip out of or into the socket when the blind isclosed, but at no other time. A small boss, 6, on the under side of ecatches into notch (1 when the blind is thrown open by the lateral playof the pintle in the socket, and holds the blind open.

In cases where a single blind is used on a window, or where there isdanger of the center line of the double blinds sagging, I affix a hookor catch, G, (shown detached in Fig. 4,) which, when the blind isclosed, passes over a staple, g, or other equivalent fixture, upon thecap of the window-frame, and, when the blind is thrown out at thebottom, hooks over said staple and forms a joint or supporting-hinge atthat point.

Having thus fully described my improvements in hanging window blinds,&c., I claim- 1. The combination of the double-pivoted hinge A B O andthe slotted detaching-hinge E D, substantially as and for the purposesspecified.

2. The combination of the hook-joint G g with the double-pivoted hinge AB O, as and for the purposes herein set forth.

3. The detaching-hinge E D, having a slotted thimble or socket, d, andpintle e, as and for the purposes set forth.
